Abstract:
In this paper, the concrete 3D printing manufacturing process of the company Aeditive is analysed with regard to productivity, quality, feasibility and economic efficiency. As a basis for this, the production processes of the precast plant of HABAU Deutschland GmbH are described. On the other hand, an overview of important research approaches at universities as well as international companies in the field of additive manufacturing is given. In the context of this potential analysis, the manufacturing process for prefabricated parts of the company Aeditive, which is preferred by HABAU, is specifically addressed. The focus of the work is on the cost comparison of additively and conventionally manufactured components. For this purpose, four comparative components from HABAU's range of prefabricated parts are compared in two different scenarios. The evaluation of the results shows that certain prefabricated parts can be manufactured more cost-efficiently with the 3D printing system than with conventional production. Another result of the work is the proof of a significant reduction in production times as well as a saving in labour, which is an important criterion for HA-BAU in times of a shortage of skilled workers. This potential analysis additionally serves the company in its decision to invest in an innovative technology.
